//@DESCRIPTION: This component provides classes that implement decimal
// floating-point types that conform in layout, encoding and operations to the
// IEEE-754 2008 standard.  This component also provides two facets to support
// standard C++ streaming operators as specified by ISO/IEC TR-24733:2009.
// These classes are 'bdldfp::Decimal32' for 32-bit Decimal floating point
// numbers, 'bdldfp::Decimal64' for 64-bit Decimal floating point numbers, and
// 'bdldfp::Decimal128' for 128-bit decimal floating point numbers.
//
// Decimal encoded floating-point numbers are important where exact
// representation of decimal fractions is required, such as in financial
// transactions.  Binary encoded floating-point numbers are generally optimal
// for complex computation but cannot exactly represent commonly encountered
// numbers such as 0.1, 0.2, and 0.99.
//
// NOTE: Interconversion between binary and decimal floating-point values is
// fraught with misunderstanding and must be done carefully and with intent,
// taking into account the provenance of the data.  See the discussion on
// conversion below and in the 'bdldfp_decimalconvertutil' component.
//
// The BDE decimal floating-point system has been designed from the ground up
// to be portable and support writing portable decimal floating-point user
// code, even for systems that do not have compiler or native library support
// for it; while taking advantage of native support (such as ISO/IEC TR
// 24732 - C99 decimal TR) when available.
//
// 'bdldfp::DecimalNumGet' and 'bdldfp::DecimalNumPut' are IO stream facets.
//
///Floating-Point Primer
///---------------------
// There are several ways of represent numbers when using digital computers.
// The simplest would be an integer format, however such a format severely
// limits the range of numbers that can be represented; and it cannot represent
// real (non-integer) numbers directly at all.  Integers might be used to
// represent real numbers of limited precision by treating them as a multiple
// of the real value being represented; these are often known as fixed-point
// numbers.  However general computations require higher precision and a larger
// range than integer and fixed point types are able to efficiently provide.
// Floating-point numbers provide what integers cannot.  They are able to
// represent a large range of real values (although not precisely) while using
// a fixed (and reasonable) amount of storage.
//
// Floating-point numbers are constructed from a set of significant digits of a
// radix on a sliding scale, where their position is determined by an exponent
// over the same radix.  For example let's see some 32bit decimal (radix 10)
// floating-point numbers that have maximum 7 significant digits (significand):
//..
//   Significand | Exponent | Value        |
//  -------------+----------+--------------+  In the Value column you may
//       1234567 |        0 |   1234567.0  |  observer how the decimal point
//       1234567 |        1 |  12345670.0  |  is "floating" about the digits
//       1234567 |        2 | 123456700.0  |  of the significand.
//       1234567 |       -1 |    123456.7  |
//       1234567 |       -2 |     12345.67 |
//..
// Floating-point numbers are standardized by IEEE-754 2008, in two major
// flavors: binary and decimal.  Binary floating-point numbers are supported by
// most computer systems in the forms of the 'float', 'double' and
// 'long double' fundamental data types.  While they are not required to be
// binary that is almost always the choice on modern binary computer
// architectures.
//
///Floating-Point Peculiarities
/// - - - - - - - - - - - - - -
// Floating-point approximation of real numbers creates a deliberate illusion.
// While it looks like we are working with real numbers, floating-point
// encodings are not able to represent real numbers precisely since they have a
// restricted number of digits in the significand.  In fact, a 64 bit
// floating-point type can represent fewer distinct values than a 64 bit binary
// integer.  Yet, because floating-point encodings can represent numbers over a
// much larger range, including extremely small (fractional) numbers, they are
// useful in practice.
//
// Floating-point peculiarities may be split into three categories: those that
// are due to the (binary) radix/base, those that are inherent properties of
// any floating-point representation and finally those that are introduced by
// the IEEE-754 2008 standard.  Decimal floating-point addresses the first set
// of surprises only; so users still need to be aware of the rest.
//
//: 1 Floating-point types cannot exactly represent every number in their
//:   range.  The consequences are surprising and unexpected for the newcomer.
//:   For example: when using binary floating-point numbers, the following
//:   expression is typically *false*: '0.1 + 0.2 == 0.3'.  The problem is not
//:   limited to binary floating-point.  Decimal floating-point cannot
//:   represent the value of one third exactly.
//:
//: 2 Unlike with real numbers, the order of operations on floating-point
//:   numbers is significant, due to accumulation of round off errors.
//:   Therefore floating-point arithmetic is neither commutative nor
//:   transitive.  E.g., 2e-30 + 1e30 - 1e-30 - 1e30 will typically produce 0
//:   (unless your significand can hold 60 decimal digits).  Alternatively,
//:   1e30 - 1e30 + 2e-30 - 1e-30 will typically produce 1e-30.
//:
//: 3 IEEE floating-point types can have special values: negative zero,
//:   negative and positive infinity; and they can be NaN (Not a Number, in two
//:   variants: quiet or signaling).  A NaN (any variant) is never equal to
//:   anything else - including NaN or itself!
//:
//: 4 In IEEE floating-point there are at least two representations of 0, the
//:   positive zero and negative zero.  Consequently unary - operators change
//:   the sign of the value 0; therefore leading to surprising results: if
//:   'f == 0.0' then '0 - f' and '-f' will not result in the same value,
//:   because '0 - f' will be +0.0' while '-f' will be -0.0.
//:
//: 5 Most IEEE floating-point operations (like arithmetic) have implicit input
//:   parameters and output parameters (that do not show up in function
//:   signatures.  The implicit input parameters are called *attributes* by
//:   IEEE while the outputs are called status flags.  The C/C++ programming
//:   language defines a so-called floating-point environment that contains
//:   those attributes and flags ('<fenv.h>' C and '<cfenv>' C++ headers).  To
//:   learn more about the floating point environment read the subsection of
//:   the same title, but first make sure you read the next point as well.
//:
//: 6 IEEE floating-points overloads some very common programming language
//:   terms: *exception*, *signal* and *handler* with IEEE floating-point
//:   specific meanings that are not to be confused with C or C++ or Posix
//:   terms of the same spelling.  Floating-point exceptions are events that
//:   occur when a floating-point operations on the specified operands is
//:   unable to produce a perfect outcome; such as when the result of an
//:   operation is inexact.  When a floating point exception occurs the
//:   (floating-point) - and reporting it is requested by a so-called trap
//:   attribute - the implementation signals the user(*) by invoking a default
//:   or a user-defined handler.  None of the words *exception*, *signal*, and
//:   *handler* used above have nothing to do with C++ exceptions, Posix
//:   signals and the handlers of those.  (To complicate matters more, C and
//:   Posix has decided to implement IEEE floating-point exception reporting as
//:   C/Posix signals - and therefore rendered them mostly useless.)
//:
//: 7 While a 32bit integer is a quite useful type for (integer) calculations,
//:   a 32bit floating-point type has such low accuracy (its significand is so
//:   short) that it is all but useless for calculation.  Such types are called
//:   "interchange formats" by the IEEE standard and should not be used for
//:   calculations.  (Except in special circumstances and by floating-point
//:   experts.  Even a 16 bit binary floating-point type can be useful for an
//:   expert in special circumstances, for example in graphics acceleration
//:   hardware.)
//
// Notes:
//   (*) IEEE Floating-point user is any person, hardware or software that uses
//       the IEEE floating-point implementation.
//
///Floating-Point Environment
/// - - - - - - - - - - - - -
// NOTE: We currently do not give access to the user to the floating-point
// environment used by our decimal system, so description of it here is
// preliminary and generic.  Note that since compilers and the C library
// already provides a (possibly binary floating-point only) environment and we
// cannot change that, our decimal floating-point environment implementation
// cannot conform to the C and C++ TRs (because those require extending the
// existing standard C library functions).
//
// The floating-point environment provides implicit input and output parameters
// to floating-point operations (that are defined to use them).  IEEE defined
// those parameters in principle, but how they are provided is left up to be
// designed/defined by the implementors of the programming languages.
//
// C (and consequently C++) decided to provide a so-called floating-point
// environment that has "thread storage duration", meaning that each thread of
// a multi-threaded program will have its own distinct floating-point
// environment.
//
// The C/C++ floating-point environment consists of 3 major parts: the rounding
// mode, the traps and the status flags.
//
///Rounding Direction in The Environment
///-  -  -  -  -  -  -  -  -  -  -  -  -
// A floating-point *rounding direction* determines how is the significand of a
// higher (or infinite) precision number get rounded to fit into the limited
// number of significant digits (significand) of the floating-point
// representation that needs to store it as a result of an operation.  Note
// that the rounding is done in the radix of the representation, so binary
// floating-point will do binary rounding while decimal floating-point will do
// decimal rounding - and not all rounding modes are useful with all radixes.
// An example of a generally applicable rounding mode would be 'FE_TOWARDZERO'
// (round towards zero).
//
// Most floating point operations in C and C++ do not take a rounding direction
// parameter (and the ones that are implemented as operators simply could not).
// When such operations (that do not have an explicit rounding direction
// parameter) need to do rounding, they use the rounding direction set in the
// floating-point environment (of their thread of execution).
//
///Status Flags
///  -  -  -  -
// Floating point operations in C and C++ do not take a status flag output
// parameter.  They report an important events (such as underflow, overflow or
// in inexact (rounded) result) by setting the appropriate status flag in the
// floating-point environment (of their thread of execution).  (Note that this
// is very similar to how flags work in CPUs, and that is not a coincidence.)
// The flags work much like individual, boolean 'errno' values.  Operations may
// set them to true.  Users may examine them (when interested) and also reset
// them (set them to 0) before an operation.
//
///Floating-Point Traps
/// -  -  -  -  -  -  -
// IEEE says that certain floating-point events are floating-point exceptions
// and they result in invoking a handler.  It may be a default handler (set a
// status flag and continue) or a user defined handler.  Floating point traps
// are a C invention to enable "sort-of handlers" for floating point
// exceptions, but unfortunately they all go to the same handler: the 'SIGFPE'
// handler.  To add insult to injury, setting what traps are active (what will)
// cause a 'SIGFPE') is not standardized.  So floating-point exceptions and
// handlers are considered pretty much useless in C.  (All is not lost, since
// we do have the status flags.  An application that wants to know about
// floating-point events can clear the flags prior to an operation and check
// their values afterwards.)
//
/// Error Reporting
///-  -  -  -  -  -
// The 'bdldfp_decimalutil' utility component provides a set of decimal math
// functions that parallel those provided for binary floating point in the C++
// standard math library.  Errors during computation of these functions (e.g.,
// domain errors) will be reported through the setting of 'errno' as described
// in the "Status Flags" section above.  (Note that this method of reporting
// errors is atypical for BDE-provided interfaces, but matches the style used
// by the standard functions.)
//
///Floating-Point Terminology
/// - - - - - - - - - - - - -
// A floating-point representation of a number is defined as follows:
// 'sign * significand * BASE^exponent', where sign is -1 or +1, significand is
// an integer, BASE is a positive integer (but usually 2 or 10) and exponent is
// a negative or positive integer.  Concrete examples of (decimal) numbers in
// the so-called scientific notation are: 123.4567 is 1.234567e2, while
// -0.000000000000000000000000000000000000001234567 would be -1.234567e-41.
//
//: "base":
//:    the number base of the scaling used by the exponent; and by the
//:    significand
//:
//: "bias":
//:    the number added to the exponent before it is stored in memory; 101, 398
//:    and 6176 for the 32, 64 and 128 bit types respectively.
//:
//: "exponent":
//:    the scaling applied to the significand is calculated by raising the base
//:    to the exponent (which may be also negative)
//:
//: "quantum":
//:     (IEEE-754) the value of one unit at the last significant digit
//:     position; in other words the smallest difference that can be
//:     represented by a floating-point number without changing its exponent.
//:
//: "mantissa":
//:    the old name for the significand
//:
//: "radix":
//:    another name for base
//:
//: "sign":
//:    +1 or -1, determines if the number is positive or negative.  It is
//:    normally represented by a single sign bit.
//:
//: "significand":
//:    the significant digits of the floating-point number; the value of the
//:    number is: 'sign * significand * base^exponent'
//:
//: "precision":
//:    the significant digits of the floating-point type in its base
//:
//: "decimal precision":
//:    the maximum significant decimal digits of the floating-point type
//:
//: "range":
//:    the smallest and largest number the type can represent.  Note that for
//:    floating-point types there are at least *two* interpretations of
//:    minimum.  It may be the largest negative number *or* the smallest number
//:    in absolute value) that can be represented.
//:
//: "normalized number":
//:    '1 <= significand <= base'
//:
//: "normalization":
//:    finding the exponent such as '1 <= significand <= base'
//:
//: "denormal number":
//:    'significand < 1'
//:
//: "densely packed decimal":
//:    one of the two IEEE significand encoding schemes
//:
//: "binary integer significand":
//:    one of the two IEEE significand encoding schemes
//:
//: "cohorts":
//:    equal numbers encoded using different exponents (to signify accuracy)
//
///Decimal Floating-Point
///----------------------
// Binary floating-point formats give best accuracy, they are the fastest (on
// binary computers), and were carefully designed by IEEE to minimize rounding
// errors (errors due to the inherent imprecision of floating-point types)
// during a lengthy calculation.  This makes them the best solution for and
// serious scientific computation.  However, they have a fatal flow when it
// comes to numbers and calculations that involve humans.  Humans think in base
// 10 - decimal.  And as the example has shown earlier, binary floating-point
// formats are unable to precisely represent very common decimal real numbers;
// with binary floating-point '0.1 + 0.2 != 0.3'.  (Why?  Because none of the
// three numbers in that expression have an exact binary floating-point
// representation.)
//
// Financial calculations are governed by laws and expectations that are based
// on decimal (10 based) thinking.  Due to the inherent limitations of the
// binary floating-point format, doing such decimal based calculations and
// algorithms using binary floating-point numbers is so involved and hard that
// that it is considered not feasible.  The IEEE-754 committee have recognized
// the issue and added specifications for 3 decimal floating-point types into
// their 2008 standard: the 32, 64 and 128 bits decimal floating-point formats.
//
// Floating-point types are carefully designed trade-offs between saving space
// (in memory), CPU cycles (for calculations) and still provide useful accuracy
// for computations.  Decimal floating-point types represent further
// compromises (compared to binary floating-points) in being able to represent
// less numbers (than their binary counterparts) and being slower, but
// providing exact representations for the numbers humans care about.
//
// In decimal floating-point world '0.1 + 0.2 == 0.3', as humans expect;
// because each of those 3 numbers can be represented *exactly* in a decimal
// floating-point format.
//
///*WARNING*: Conversions from 'float' and 'double'
/// - - - - - - - - - - - - - - - - - - - - - - - -
// Clients should *be* *careful* when using the conversions from 'float' and
// 'double' provided by this component.  In situations where a 'float' or
// 'double' was originally obtained from a decimal floating point
// representation (e.g., a 'bdldfp::Decimal', or a string, like "4.1"), the
// conversions in 'bdldfp_decimalconvertutil' will provide the correct
// conversion back to a decimal floating point value.  The conversions in this
// component provide the closest decimal floating point value to the supplied
// binary floating point representation, which may replicate imprecisions
// required to initially approximate the value in a binary representation.
// The conversions in this component are typically useful when converting
// binary floating point values that have undergone mathematical operations
// that require rounding (so they are already in-exact approximations).
//
///Cohorts
///- - - -
// In the binary floating-point world the formats are optimized for the highest
// precision, range and speed.  They are stored normalized and therefore store
// no information about their accuracy.  In finances, the area that decimal
// floating-point types target, accuracy of a number is usually very important.
// We may have a number that is 1, but we know it may be 1.001 or 1.002 etc.
// And we may have another number 1, which we know to be accurate to 6
// significant digits.  We would display the former number as '1.00' and the
// latter number as '1.00000'.  The decimal floating-point types are able to
// store both numbers *and* their precision using so called cohorts.  The
// '1.00' will be stored as '100e-2' while '1.00000' will be stored as
// '100000e-5'.
//
// Cohorts compare equal, and mostly behave the same way in calculation except
// when it comes to the accuracy of the result.  If I have a number that is
// accurate to 5 digits only, it would be a mistake to try to expect more than
// 5 digits accuracy from a calculation involving it.  The IEEE-754 rules of
// cohorts (in calculations) ensures that results will be a cohort that
// indicates the proper expected accuracy.
//
///Standards Conformance
///---------------------
// The component has also been designed to resemble the C++ Decimal
// Floating-Point Technical Report ISO/IEC TR-24733 of 2009 and its C++11
// updates of ISO/IEC JTC1 SC22 WG21 N3407=12-0097 of 2012 as much as it is
// possible with C++03 compilers and environments that do not provide decimal
// floating-point support in any form.
//
// At the time of writing there is just one standard about decimal-floating
// point, the IEEE-754 2008 standard and the content of this component conforms
// to it.  The component does not fully implement all required IEEE-754
// functionality because due to our architectural design guidelines some of
// these must go into a separate so-called utility component.)
//
// The component uses the ISO/IEC TR 24732 - the C Decimal Floating-Point
// TR - in its implementation where it is available.
//
// The component closely resembles ISO/IEC TR 24733 - the C++ Decimal
// Floating-Point TR - but does not fully conform to it for several reasons.
// The major reasons are: it is well known that TR 24733 has to change before
// it is included into the C++ standard; the TR would require us to change
// system header files we do not have access to.
//
// In the following subsections the differences to the C++ technical report are
// explained in detail, including a short rationale.
//
///No Namespace Level Named Functions
/// - - - - - - - - - - - - - - - - -
// BDE design guidelines do not allow namespace level functions other than
// operators and aspects.  According to BDE design principles all such
// functions are placed into a utility component.
//
///All Converting Constructors from Integer Types are Explicit
///- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
// This change is necessary to disable the use of comparison operators without
// explicit casting.  See No Heterogeneous Comparisons Without Casting.
//
///No Heterogeneous Comparisons Without Casting
/// - - - - - - - - - - - - - - - - - - - - - -
// The C and C++ Decimal TRs refer to IEEE-754 for specifications of the
// heterogeneous comparison operators (comparing decimal floating-point types
// to binary floating-point types and integer types); however IEEE-754 does
// *not* specify such operations - leaving them unspecified.  To make matters
// worse, there are two possible ways to implement those operators (convert the
// decimal to the other type, or convert the other type to decimal first) and
// depending on which one is chosen, the result of the operator will be
// different.  Also, the C committee is considering the removal of those
// operators.  We have removed them until we know how to implement them.
// Comparing decimal types to those other types is still possible, it just
// requires explicit casting/conversion from the user code.
//
///Arithmetic And Computing Support For 'Decimal32'
/// - - - - - - - - - - - - - - - - - - - - - - - - -
// IEEE-754 designates the 32 bit floating-point types "interchange formats"
// and does not require or recommend arithmetic or computing support of any
// kind for them.  The C (and consequently the C++) TR goes against the IEEE
// design and requires '_Decimal32' (and 'std::decimal32') to provide computing
// support, however, in a twist, allows it to be performed using one of the
// larger types (64 or 128 bits).  The rationale from the C committee is that
// small embedded systems may need to do their calculations using the small
// type (so they have made it mandatory for everyone).  To conform the
// requirement we provide arithmetic and computing support for Decimal32 type
// but users need to be aware of the drawbacks of calculations using the small
// type. Industry experience with the 'float' C type (32bit floating-point
// type, usually binary) has shown that enabling computing using small
// floating-point types are a mistake that causes novice programmers to write
// calculations that are very slow and inaccurate.
//
// We recommend what IEEE recommends: convert your 32 bit types on receipt to a
// type with higher precision (usually 64 bit will suffice), so you
// calculations using that larger type, and convert it back to 32 bit type only
// if your output interchange format requires it.
//
///Non-Standard Member Functions
///- - - - - - - - - - - - - - -
// Due to BDE rules of design and some implementation needs we have extended
// the C++ TR mandated interface of the decimal floating-point types to include
// support for accessing the underlying data (type), to parse literals for the
// portable literal support.
//
// Note that using any of these public member functions will render your code
// non-portable to non-BDE (but standards conforming) implementations.
//
///'Decimal32' Type
///----------------
// A basic format type that supports input, output, relational operators
// construction from the TR mandates data types and arithmetic or operations.
// The type has the size of exactly 32 bits.  It supports 7 significant decimal
// digits and an exponent range of -95 to 96.  The smallest non-zero value that
// can be represented is 1e-101.
//
// Portable 'Decimal32' literals are created using the 'BDLDFP_DECIMAL_DF'
// macro.
//
///'Decimal64' Type
///----------------
// A basic format type that supports input, output, relational operators
// construction from the TR mandates data types and arithmetic or operations.
// The type has the size of exactly 64 bits.  It supports 16 significant
// decimal digits and an exponent range of -383 to 384.  The smallest non-zero
// value that can be represented is 1e-398.
//
// Portable 'Decimal64' literals are created using the 'BDLDFP_DECIMAL_DD'
// macro.
//
///'Decimal128' Type
///-----------------
// A basic format type that supports input, output, relational operators
// construction from the TR mandates data types and arithmetic or operations.
// The type has the size of exactly 128 bits.  It supports 34 significant
// decimal digits and an exponent range of -6143 to 6144.  The smallest
// non-zero value that can be represented is 1e-6176.
//
// Portable 'Decimal128' literals are created using the 'BDLDFP_DECIMAL_DL'
// macro.
//
///Decimal Number Formatting
///-------------------------
// Streaming decimal floating point numbers to an output stream supports
// formatting flags for width, capitalization and justification and flags used
// to output numbers in natural, scientific and fixed notations.  When
// scientific or fixed flags are set then the precision manipulator specifies
// how many digits of the decimal number are to be printed, otherwise all
// significant digits of the decimal number are output using native notation.
//
///User-defined literals
///---------------------
// The user-defined literal 'operator "" _d32', 'operator "" _d64', and
// 'operator "" _d128' are declared for the 'bdldfp::Decimal32',
// 'bdldfp::Decimal64', and 'bdldfp::Decimal128' types respectively .  These
// user-defined literal suffixes can be applied to both numeric and string
// literals, (i.e., 1.2_d128, "1.2"_d128 or "inf"_d128) to produce a decimal
// floating-point value of the indicated type by parsing the argument string
// or numeric value:
//..
//  using namespace bdldfp::DecimalLiterals;
//
//  bdldfp::Decimal32   d0  = "1.2"_d32;
//  bdldfp::Decimal32   d1  =  1.2_d32;
//  assert(d0 == d1);
//
//  bdldfp::Decimal64   d2  = "3.45678901234"_d64;
//  bdldfp::Decimal64   d3  =  3.45678901234_d64;
//  assert(d2 == d3);

// The operators providing literals are available in the
// 'BloombergLP::bdldfp::literals::DecimalLiterals' namespace (where 'literals'
// and 'DecimalLiterals' are both inline namespaces). Because of inline
// namespaces, there are several viable options for a using declaration, but
// *we* *recommend* 'using namespace bdldfp::DecimalLiterals', which minimizes
// the scope of the using declaration.
//
// Note that the parsing follows the rules as specified for the 'strtod32',
// 'strtod64' and 'strtod128' functions in section 9.6 of the ISO/EIC TR 247128
// C Decimal Floating-Point Technical Report.
//
// Also note that these operators can be used only if the compiler supports
// C++11 standard.

///Usage
///-----
// In this section, we show the intended usage of this component.
//
///Example 1: Portable Initialization of Non-Integer, Constant Values
/// - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
// If your compiler does not support the C Decimal TR, it does not support
// decimal floating-point literals, only binary floating-point literals.  The
// problem with binary floating-point literals is the same as with binary
// floating-point numbers in general: they cannot represent the decimal numbers
// we care about.  To solve this problem there are 3 macros provided by this
// component that can be used to initialize decimal floating-point types with
// non-integer values, precisely.  These macros will evaluate to real, C
// language literals where those are supported and to a runtime-parsed solution
// otherwise.  The following code demonstrates the use of these macros as well
// as mixed-type arithmetics and comparisons:
//..
//  bdldfp::Decimal32  d32( BDLDFP_DECIMAL_DF(0.1));
//  bdldfp::Decimal64  d64( BDLDFP_DECIMAL_DD(0.2));
//  bdldfp::Decimal128 d128(BDLDFP_DECIMAL_DL(0.3));
//
//  assert(d32 + d64 == d128);
//  assert(bdldfp::Decimal64(d32)  * 10 == bdldfp::Decimal64(1));
//  assert(d64  * 10 == bdldfp::Decimal64(2));
//  assert(d128 * 10 == bdldfp::Decimal128(3));
//..
//
///Example 2: Precise Calculations with Decimal Values
///- - - - - - - - - - - - - - - - - - - - - - - - - -
// Suppose we need to add two (decimal) numbers and then tell if the result is
// a particular decimal number or not.  That can get difficult with binary
// floating-point, but easy with decimal:
//..
//  if (std::numeric_limits<double>::radix == 2) {
//    assert(.1 + .2 != .3);
//  }
//  assert(BDLDFP_DECIMAL_DD(0.1) + BDLDFP_DECIMAL_DD(0.2)
//      == BDLDFP_DECIMAL_DD(0.3));

    //:   return a decimal object of the return type initialized to infinity
    //:   with the same sign.

    //: o Otherwise if 'str' represents a value that has an absolute value that

    // function in section 9.6 of the ISO/EIC TR 247128 C Decimal
    // Floating-Point Technical Report.
    //
    // Also note that the numeric literal version omits the optional leading
    // sign in 'str'.  For example, if the string is -1.2_d64 then the string
    // "1.2" is passed to the one-argument form, not "-1.2", because leading
    // signs are operators, not parts of literals.  On the other hand, the
    // string literal version does not omit leading sign and if the string is
    // "-1.2"_d64 then the string "-1.2" is passed to the two-argument form.
    //
    // Also note that the quantum of the resultant value is affected by the
    // number of decimal places in 'str' string in both numeric and string
    // literal formats starting with the most significand digit and cannot
    // exceed the maximum number of digits necessary to differentiate all
    // values of the indicated return type, for example:
    //
    // '0.015_d64;               =>              15e-3'
    // '1.5_d64;                 =>              15e-1'

    // applied to both numeric and string literals, (i.e., 1.2_d128, "1.2"_d128
    // or "inf"_d128). The resulting decimal object is initialized as follows:
    //
    //: o If 'str' does not represent a floating-point value, then return a
    //:   decimal object of the indicated return type initialized to a NaN.
    //:
    //: o Otherwise if 'str' represents infinity (positive or negative), then
    //:   return a decimal object of the indicated return type initialized to
    //:   infinity value with the same sign.
    //:
    //: o Otherwise if 'str' represents zero (positive or negative), then
    //:   return a decimal object of the indicated return type initialized to
    //:   zero with the same sign.
    //:
    //: o Otherwise if 'str' represents a value that has an absolute value that
    //:   is larger than the maximum value supported by the indicated return
    //:   type, then store the value of the macro 'ERANGE' into 'errno' and
    //:   return a decimal object of the return type initialized to infinity
    //:   with the same sign.
    //:
    //: o Otherwise if 'str' represents a value that has an absolute value that
    //:   is smaller than min value of the indicated return type, then store
    //:   the value of the macro 'ERANGE' into 'errno' and return a decimal
    //:   object of the return type initialized to zero with the same sign.
    //:
    //: o Otherwise if 'str' has a value that is not exactly representable
    //:   using the maximum digit number supported by the indicated return
    //:   type, then return a decimal object of the return type initialized to
    //:   the value represented by 'str' rounded according to the rounding
    //:   direction.
    //:
    //: o Otherwise return a decimal object of the indicated return type
    //:   initialized to the decimal value representation of 'str'.
    //
    // Note that the parsing follows the rules as specified for the 'strtod128'
    // function in section 9.6 of the ISO/EIC TR 247128 C Decimal
    // Floating-Point Technical Report.
    //
    // Also note that the numeric literal version omits the optional leading
    // sign in 'str'.  For example, if the string is -1.2_d128 then the string
    // "1.2" is passed to the one-argument form, not "-1.2", because leading
    // signs are operators, not parts of literals.  On the other hand, the
    // string literal version does not omit leading sign and if the string is
    // "-1.2"_d128 then the string "-1.2" is passed to the two-argument form.
    //
    // Also note that the quantum of the resultant value is affected by the
    // number of decimal places in 'str' string in both numeric and string
    // literal formats starting with the most significand digit and cannot
    // exceed the maximum number of digits necessary to differentiate all
    // values of the indicated return type, for example:
    //
    // '0.015_d128;                  =>                                 15e-3'
